Aeronautics Days, 19th – 21st June 2006

Introduction (1/3)

  • Automatic Dependent Surveillance –

Broadcast (ADS-B) – ADS-B allows aircraft to broadcast identification, position, velocity, intent over ranges ~ 100 NM – ADS-B ground receivers enhance information for air traffic controllers – ADS-B technology invented 1980s. Now 40% of flights in Europe equipped with ADS-B Mode S extended squitter of which half broadcasting position

ADS-B Receiver ground-station

Introduction (3/3)

  • ASAS Thematic Network 2

– Sponsored by European Commission Directorate General Research 6th Framework – Three year project from April 2005 – Aim: to accelerate the application of ASAS

  • perations in European Airspace taking into

account global applicability in order to increase airspace capacity and safety. – Managed by consortium: BAE Systems, ENAV, LFV, NLR, Thales ATM & Thales Avionics, EUROCONTROL (leader)

Aeronautics Days, 19th – 21st June 2006

Objectives

  • 5 ASAS workshops & final seminar

– Malmo (Oct 2005), Rome (Apr 2006) – Glasgow (Sep 2006), Amsterdam (2007)

  • Web-based ASAS related documentation
  • Annual assessment of the maturity of

global ADS-B/ASAS applications by ASAS-TN2 partners – Deliverables: Report ”ASAS application maturity assessment” by March 2006, updated 2007 & 2008

Aeronautics Days, 19th – 21st June 2006

Method (1/3)

  • 17 ASAS applications in clusters

– ADS-B surveillance – Airborne traffic situational awareness – ASAS spacing – ASAS separation – ASAS self-separation

  • 12 ASAS specialists from:

BAE systems (UK), ENAV (Italy), LFV (Sweden), NLR (The Netherlands), Thales ATM (France), Thales Avionics (France) and EUROCONTROL

Method (2/3)

  • Maturity metrics scale 0 to 4:

– Operational concepts – Benefits and constraints – Safety assessment – Procedures and human factors – Systems, HMI and technology – Transition issues

  • Results reviewed by 9 selected peers from US

(e.g. pilot working for Boeing) and Europe (e.g. EUROCAE)

Aeronautics Days, 19th – 21st June 2006

Method (3/3) Example metric - Operational concept

1 = Problem statement, identify solutions, concept generation (concept of operations) 2 = Preliminary Operational Concept Description (R&D Operational Service and Environment Description (OSED)) 3 = Draft Requirements Focus Group (RFG) OSED in development (e.g. from R&D OSEDs, trials and experiments, initial OSED) – mature and in review. 4 = Consolidated OSED - Published

Results (1/5) – relatively mature

Air Traffic Control surveillance in non-radar areas (ADS-B surveillance)

  • Objective: to provide ATC surveillance in

non-radar areas e.g. remote areas, offshore,

  • peration areas, any continental areas and

certain oceanic areas, which, due to traffic level or cost of equipment could not justify installation of radars.

  • Benefits:

– Surveillance with accurate position and track prediction (accuracy does not vary with range and bearing) – Controller can provide radar-like separation services instead of procedural

  • Implementation considerations

– No detrimental impact on flight crew – Large network of ground ADS-B receivers

Results (2/5) – relatively mature

Air Traffic Control surveillance in non-radar areas (ADS-B surveillance)

  • European R&D projects:

NUP-1 & 2, MEDUP, SEAP

  • EUROCONTROL CASCADE

CRISTAL validation trials

  • Australia plan daily

nationwide upper airspace coverage by 2007

  • Capstone Alaska since 2001
  • ICAO OPLINK and SASP

developing separation standards

Results (3/5) – medium maturity

In-trail procedure in non-radar oceanic airspace (Airborne traffic situational awareness)

  • Objective: to allow in-trail ADS-B equipped aircraft in non-radar
  • ceanic airspace, which may not be longitudinally separated

from each other, to climb or descend through each other’s flight levels.

  • Benefits: Improved utilisation of the North Atlantic
  • ceanic airspace by facilitating a higher

rate of flight level changes yielding better flight efficiency (e.g. fuel savings, increased payload, reduced gaseous emissions, avoiding turbulent flight levels)

  • Benefits identified
  • Safety – Operational Hazard

Analysis on-going

  • Procedures – defined in OSED

Results (5/5) – low maturity

Enhanced crossing and passing (ASAS spacing)

  • Objective: to provide

controller with new set of instructions to solve conflicts e.g. directing flight crews to cross or pass designated traffic aircraft while maintaining a given spacing value.

  • Immaturity due to similar

application in ASAS separation being preferred
